It's not really clicking woth me either. Shouldn't a policy really
just be as simple as:
* 3 digits: interface (major), implementation (minor), patch
* change the major number only when you have changed the API
* change the minor number each time you add a significant feature
and want to share the release
* change the patch number each time you do something
OK, a bit more detail, but not much.

RubyGems is already making life easier for the user. I don't think
asking for confirmation of automatic downloads is "putting too much
burden" on them.
At any time, you should be able to ask what the dependencies of an
installed gem are. And it should tell you what you have installed to
match those dependencies. That's not difficult.
